Disclosed is a process for preparing an optically active 1-aryl- or 2-aryl-alkylamines of formulas Ia, Ib and Ic with high optical purity and high yield. The process uses an optically active 1- or 2-naphthylglycolic acid of the general formula II as a resolving agent. Also disclosed is a process for praparing an optically active 1- or 2-naphthylglycolic acid of formula II using an optically active 1-aryl- or 2-aryl-alkylamines of formulas Ia, Ib and Ic as the resolving agents
揭示了一种制备具有高光学纯度和高收率的光学活性1-芳基或2-芳基-烷基胺(化学式Ia、Ib和Ic)的方法。该方法使用光学活性的1-或2-萘甘醇酸(通式II)作为分离剂。还揭示了一种使用光学活性的1-芳基或2-芳基-烷基胺(化学式Ia、Ib和Ic)作为分离剂,制备光学活性的1-或2-萘甘醇酸(化学式II)的方法。
